Title:
SYSTEM AND METHOD FOR EXTRACTION OF METAL VALUES FROM ACTIVE MATERIAL OF LITHIUM-ION BATTERIES
Document Type and Number:
WIPO Patent Application WO/2023/148760
Kind Code:
A1
Abstract:
The various embodiments of the present invention provide a system and method for extraction of metal values from active material of Lithium-ion batteries. The system comprises a separation module and an extraction module. The extraction module further comprises an inert container, a furnace apparatus, a quenching apparatus, a filtration mechanism and a wet magnetic separation apparatus. The black mass obtained from the separation process is heated in a furnace and then quenched. The suspension is then filtered, and the solution is then evaporated to extract Lithium values. The filtrate residue is subjected to wet magnetic separation, where the magnetic material comprises Cobalt, Nickel and a plurality of other elements in the form of a non-magnetic mass.
